Description
CATO supplies 4-[4-(Methanesulfonyloxy)-1-butynyl]-a,a-di(methyl-d3)benzeneacetic Acid, Methyl Ester (CAS 1020719-58-7), a certified reference material (molecular formula C16H20O5S, MW 324.39 g/mol) for analytical method development and quality control.
The molecular framework of 4-[4-(Methanesulfonyloxy)-1-butynyl]-a,a-di(methyl-d3)benzeneacetic Acid, Methyl Ester (C16H20O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
